3. Transmission Process FIG. 3 is a flowchart showing a transmission process when the terminal device 10 transmits print data. FIGS. 4 and 5 are flowcharts showing the addition determination process and the additional data transmission process in the transmission process, respectively.

  In the transmission processing in the present embodiment, for example, the user sets print setting information (an example of printing conditions) in print data to be transmitted by a program such as a printer driver via the operation unit 15 and the display unit 17 of the terminal device 10. This process is executed by the CPU 11 when a transmission button for setting and instructing transmission of the print data is pressed.

Note that the print setting information referred to here is information specifying the destination printer 30, single-sided printing for printing on one side of the sheet W or printing on both sides of the sheet W when printing is performed by the printer 30. Information indicating whether printing is performed, information indicating whether monochrome printing is performed using only B toner or color printing is performed using four colors of toner.

  Furthermore, Nin1 printing that prints information on multiple pages of page data on a single sheet W, information indicating whether low-resolution printing is performed by reducing the printing resolution, or high-resolution printing that is performed by increasing the printing resolution. (N indicates the number of page data to be printed on one sheet), when the sheet W is fed (one sheet is picked up by the pick-up rollers 46 and 72) or manually fed Information indicating which of the trays 70 is to be used.

  When the above-described transmission button is pressed on the terminal device 10, as shown in FIG. 3, the CPU 11 executes an addition determination process for determining whether or not to add the additional data F to the print data in S101.

  In the addition determination process, as shown in FIG. 4, the CPU 11 acquires print setting information and analyzes print data in S201. Here, the acquisition of the print setting information is to acquire the various types of print setting information described above. In the analysis of the print data, the confidential keyword is analyzed from the text data described in the print data (an example of the printing condition), and the size of the print area in one sheet W of the print data is analyzed ( An example of printing conditions).

The confidential keyword is used to determine whether the print data is confidential.
For example, keywords such as “confidential”, “secret”, “confidential”, etc., personal information such as telephone numbers, addresses, and the like correspond thereto.

  When the process of S201 is completed, it is determined in S202 whether or not double-sided printing is set in the print setting information acquired in S201. If double-sided printing is set (S202: YES), it is determined in S203 that the additional data F is not added to the print data, and the addition determination process ends.

  On the other hand, if double-sided printing is not set in S202 and single-sided printing is set (S202: NO), whether or not the above-described confidential keyword is included in the print data analyzed in S201 in S204. Is judged. If the print data includes a confidential keyword (is present) (S204: YES), it is determined in S203 that the additional data F is not added to the print data, and the addition determination process ends.

  On the other hand, if there is no confidential keyword in S204 (S203: NO), it is determined in S205 whether monochrome printing is set in the print setting information acquired in S201. If monochrome printing is set (S205: YES), it is determined in S206 that the additional data F is to be added to the print data, and the addition determination process ends.

  On the other hand, if monochrome printing is not set in S205 and color printing is set (S205: NO), whether or not low resolution printing is set in the print setting information acquired in S201 in S207. Is judged. If low-resolution printing is set (S207: YES), it is determined in S206 that the additional data F is added to the print data, and the addition determination process is terminated.

On the other hand, if low resolution printing is not set in S207 and high resolution printing is set (S207: NO), Nin1 printing is set in the print setting information acquired in S201 in S208. It is determined whether or not the value of is 4 or more. Here, if the value of N is set to be 4 or more (S208: YES), it is determined in S206 that the additional data F is added to the print data, and the addition determination process is terminated.

  On the other hand, if the value of N is less than 4 in S208 (S208: NO), it is determined in S209 whether the print area of the print data analyzed in S201 is a predetermined area or less. If the print area is equal to or smaller than the predetermined area (S209: YES), it is determined in S206 that the additional data F is added to the print data, and the addition determination process ends.

  On the other hand, if the print area is larger than the predetermined area in S209 (S209: NO), it is determined in S203 that the additional data F is not added to the print data, and the addition determination process ends.

  To summarize the processing from S202 to S209, if double-sided printing is set in S202 or S204, or if it is determined that a confidential keyword is included in the print data, the additional data F is stored in S203. It is determined not to be added. On the other hand, when monochrome printing is set in S205 or S207 to S209, when low-resolution printing is set, when the value of N is 4 or more in Nin1 printing, or when the printing area is a predetermined area or less Is determined to add additional data F in S206. If NO is determined in S205 and S207 to S209, it is determined that the additional data F is not added in S203.

  In the addition determination process, when the process of S203 or S206 ends and the addition determination process ends, it is determined in S102 whether or not it is determined that the additional data F is added to the print data by the addition determination process of S101. .

  If it is determined that it is determined to be added (S102: YES), additional data generation processing for generating additional data F based on the printer 30 or the like is executed in S103. In the additional data generation process, as shown in FIG. 5, in step S301, the CPU 11 feeds the printer 30 connected to the destination printer 30 and the communication line 20 (hereinafter referred to as the surrounding printer 30). Get information.

  Here, the paper feed tray information is information on trays for feeding sheets W, such as a feed tray 41 and a manual feed tray 70, which are paper feed trays, on which side of the sheet W fed from each tray. This is information indicating whether the printing unit 37 executes printing. In the printer 30 according to the present embodiment, in the case of the sheet W placed on the supply tray 41, printing is performed on the lower surface of the placed sheet W by the transport mechanism 38. On the other hand, in the case of the manual feed tray 70, printing is performed on the upper surface of the sheet W to be placed by the transport mechanism 38.

  When the processing of S301 is completed, additional data F is generated based on the respective paper feed tray information of the destination printer 30 and the surrounding printer 30 in S302, and further transmitted to the print setting information of the print data in S303. Based on the paper feed tray information of the paper feed tray (in this embodiment, the supply tray 41 or the manual feed tray 70) when printing with the previous printer 30, information on the tray is emphasized.

  The additional data F generated here is shown in FIG. FIG. 6 is an image diagram showing an example when printing is performed by adding the additional data F to the print data. The additional data F is data added to the lower part of the data “A” that is the print data.

This additional data F is data based on the paper feed tray information acquired in S301, and is provided on the surface fed and printed from each tray for each of the supply tray 41 and the manual feed tray 70, which are the paper feed trays of each printer 30. Based on this, when printing the printed sheet W again, it is information indicating which side should be placed on each paper feed tray with the surface facing upward or downward.

  In the case of the example in FIG. 6, when printing from the supply tray 41 when printing again, information is printed on the placed lower surface. In the case where paper is fed from the manual feed tray 70, it is printed on the placed upper surface. Therefore, the information is instructed to be placed with the currently printed surface as the lower surface.

  Note that “printer A” indicates the transmission destination printer 30, and the surrounding printer 30 is described as “printer B”. In this embodiment, the transmission destination printer 30 indicated as “printer A” and the surrounding printer 30 indicated as “printer B” have a common configuration, and therefore the information of the additional data F is very similar. Since there are various paper feeding and printing depending on the type of printer, the information of the additional data F may differ depending on the printer.

  Further, in this additional data F, “(the tray directly above is the paper feed tray setting at the time of printing)” is further added to the information of the supply tray 41 that is the paper feed tray for printing by the destination printer 30. Is added.

  In the additional data generation process, the process of S303 ends. When the additional data generation process ends, it is determined in S104 whether the print data is print data composed of page data of a plurality of pages. .

  At this time, if it is determined that the print data is composed of page data of a plurality of pages (S104: YES), additional data F is added to the page data of the first page in S105. On the other hand, if it is determined that the print data is composed of page data of one page (S104: NO), additional data F is added to the print data (page data of one page) in S106.

  When the processes of S105 and S106 are completed, the print data with the additional data F added is transmitted from the terminal device 10 to the destination printer 30 via the network interface 17 in S107.

  If it is determined in S102 that the additional data F is determined not to be added by the addition determination process in S101 (S102: NO), the destination printer from the terminal device 10 via the network interface 17 is determined in S107. Print data to which no additional data F is added is sent to 30.

4). According to the present embodiment, since the additional data F is added when the printer 30 transmits (prints) the print data, the user can print the printing surface of the sheet W printed by the printer 30. When printing is performed again on a different surface, appropriate placement according to the paper feed tray of the printer 30 is possible.

  Further, by determining whether or not to add the additional data F based on the print setting and the analysis (printing condition) of the print data, the additional data F is added to the print data printed under the specific printing condition. Is possible.

  Further, when the printed sheet W is printed again by the printer 30 provided with a plurality of paper feed trays, there is a possibility that the user wants to designate a paper feed tray to be used when printing again. Therefore, the convenience of the printed sheet W is increased by adding the additional data F associated with the printing surface of the sheet W placed on each paper feed tray.

  Further, when the printed sheet W is printed again by the printer 30, there is a possibility that the sheet W is used by a printer 30 different from the printed printer 30. Therefore, by adding the additional data F for different printing apparatuses, the convenience of the printed sheet is increased.

  In addition, a paper feed tray used when printing data is printed is a paper feed tray that is highly likely to be used in the future. Therefore, by adding the additional data F associated with the printing surface of the sheet W placed on the paper feed tray, it is possible to add the additional data F in accordance with the user's availability.

  Further, in the case of a bundle of sheets W printed by print data composed of page data of a plurality of pages, there is a high possibility that the sheet W is handled by the bundle of sheets W. Therefore, by adding the additional data F to the page data of at least one page of the plurality of pages, it is possible to suppress the use of toner for printing the additional data F.

  Further, for example, a sheet W on which print data set with low quality such as monochrome printing, trial printing, low image quality printing, low resolution printing, Nin1 printing, etc. may be printed again by the printer 30. Is expensive. Therefore, in such a case, it is possible to appropriately handle the print data by determining that the additional data F is added.

  In addition, for example, when printing web data, a sheet having a large margin area and almost no printing on the sheet W may be printed again by the printer 30 if the printing area is smaller than a predetermined area. Is expensive. Therefore, in such a case, it is possible to appropriately handle the print data by determining that the additional data F is added.

  In addition, for example, when a sensitive keyword is included in the print data, the image data is determined to be confidential data. The sheet W printed with such print data is unlikely to be printed again by the printer 30. Accordingly, in such a case, it is possible to appropriately handle the print data by determining that the additional data F is not added.

  In addition, for example, the setting of double-sided printing and printing on both sides of the sheet W is unlikely to be printed again by the printer 30. Accordingly, in such a case, it is possible to appropriately handle the print data by determining that the additional data F is not added.

  Further, when the sheet W is placed on the sheet feeding tray, the additional data F is added as data indicating at least one of the upper surface and the lower surface, which is convenient when the sheet W is printed again by the printer. High data can be printed.
